Noise affect people’s all kinds of activities widely, such as sleep and rest, damage to the hearing, and even cause the nervous system, cardiovascular system, digestive system diseases. In practice, we often encounter pulse signals that are extremely harmful to human body health. In this paper, active noise control of symmetric α stable (SαS) distribution impulsive noise is studied. The algorithm based on the nonlinear transformation is proposed. Compared to the previous algorithm, it does not need the parameter selection and thresholds estimation. Results prove the effectiveness of the algorithm.

Control of impulsive noise is one important challenge for the practical implementation of active noise control (ANC) systems. The advantages and disadvantages of popular filtered-X least mean square (FXLMS) ANC algorithm and nonlinear filtered-X least mean M-estimate (FXLMM) algorithm are discussed in this paper. A new modified FXLMM algorithm is also proposed to achieve better performance in controlling impulsive noise. Computer simulations are carried out for all the three algorithms and the results are presented and analyzed. The results show that the FXLMM and modified FXLMM algorithms are more robust in suppressing the adverse effect of sudden large amplitude impulses than FXLMS algorithm. In particular, the proposed modified FXLMM algorithm can achieve better stability without sacrificing the performance of residual noise when encountering impulses.
